Anybody else have issues with the bolt release button being extremely difficult to depress? Not a huge issue, I'm assuming it just needs to be broken in (only had mine at the range once so far). Just curious if anyone else had that problem.

Also, any news on aftermarket dust covers? My only complaint with this gun so far is the plastic dust cover. It is a bit longer than other AR10 covers, so no replacements available that I know of.
